About the Model 7985 StandaloneTermination Unit

1M/HDSL Overview

Hotwire� Multirate/High-bit-rate Digital Subscriber Line (M/HDSL) productsmaximize customer service areas by varying the DSL line rate. This ensuressymmetric DSL connectivity over a wide range of telephone line distances andtransmission line qualities.

Hotwire M/HDSL products can transport at full or fractional payload rates over a4-wire, full-duplex circuit over varying distances based on the conditions of the4-wire loop. Examples include support for router, multiplexer and PBXconnections at 128 kbps, with distances exceeding 29,000 feet (8.9 km) on 24 gauge (.5 mm) cable, or up to 15,000 feet (4.6 km) delivered at 2.048 Mbps on24 gauge (.5 mm) cable.

Hotwire M/HDSL is equipped with an automatic configuration capability thatreduces the M/HDSL installation process to a simple plug and play mode. Simplyconnecting the units to the line automatically configures the customer for themaximum data rate supported by the local loop. M/HDSL units can also beconfigured at fixed line speeds to achieve maximum distances.

When the remote unit detects thecommand, it sends a 511 pattern and lights the front panel test LED. Each unitwill send and monitor the 511 pattern. The duration and results of the test aredisplayed on the Network Test screen of each unit.

NOTE:The send and monitor test is not a loopback test. Each unit independentlysends and monitors a 511 pattern.

� Enable the Telnet Login Required option.

� Limit the access by setting a Session Access Level option of Operator for theTelnet Session.

� Disable the access with the Telnet Session option.

See Table A-5, Telnet Sessions Options, in Appendix A, Configuration OptionTables.

ATI Access Levels

The Model 7985 Standalone Termination Unit has two access levels:Administrator and Operator. The access level determines what functions areaccessible, as shown in Table 7-1.

Table 7-1. Access Levels

ATI Access to Menu Functions Administrator Operator

Status Read-Only Read-Only

Test Full Access No Access

Resetting the Termination Unit’s COM Port or Factory Defaults

Misconfiguring the termination unit could render the user interface inaccessible,leaving it in a state where a session cannot be started via the COM port or aTelnet session. If this occurs, the termination unit connectivity can be restored viaa terminal directly connected to the COM port.

Two methods can be used to restore access to the user interface:

� Reset COM Port – Allows you to reset the configuration options related toCOM port usage. This also causes a device reset, where the termination unitperforms a Device Self-Test. No security-related configuration options arechanged.

� Reload Factory Defaults – Allows you to reload the Default FactoryConfiguration, resetting all of the configuration and control settings whichcauses the current configuration to be destroyed and a device reset. Thismethod is also useful when the user’s password(s) have been forgotten.

� Procedure

To reset COM port settings:

1. At the terminal that is directly connected to the unit’s COM port, configure theterminal to operate at 9.6 kbps, using character length of 8 bits, with onestop-bit, and no parity.

2. Reset the unit, then immediately and repeatedly press Enter at a rate ofabout 1 press per second until the System Paused screen appears.

3. Tab to the desired method, and enter yes (or y) for the selected prompt.

IP Addressing

8Selecting an IP Addressing Scheme

The NTU’s network interface IP address is assigned through the peer IP addressof the LTU’s Network Interface menu. The NTU obtains the LTU’s IP address andsubnet mask when the PPP link is established over the EOC. The LTU IPaddress and subnet mask are configured from the Communication ProtocolOptions menu.

The Model 7985 Standalone Termination Unit is assigned an IP address andsubnet through the Peer IP address of the M/HDSL Network interface menu.Once the address is assigned, you can use the Model 7985 StandaloneTermination Unit’s ATI to assign:

� An IP address for each NMS to act as a trap manager. See Table A-7, SNMP Traps Options, in Appendix A, Configuration Option Tables.

� An IP address for the TFTP server you wish to use to upload and downloadconfigurations. See Configuration Loader in Chapter 3, Initial Setup andConfiguration.

Review the following information in preparation for selecting an IP addressingscheme.

� Any legal host address is allowed for a given subnet. The address choicewithin the subnet is arbitrary.

� A single route to a subnet is all that is needed to reach every device on asubnet.
